Cisco Auditing Tool & Cisco Global Exploiter to Exploit 14 Vulnerabilities in Cisco Switches and Routers

Cisco Global Exploiter (CGE)

Cisco Global Exploiter (CGE), is an advanced, simple and fast security testing tool / exploit engine, that is able to exploit 14 vulnerabilities in disparate Cisco s witches and routers.  CGE is command-line driven perl script which has a simple and easy to use front-end.

CGE can exploit the following 14 vulnerabilities:

[1] – Cisco 677/678 Telnet Buffer Overflow Vulnerability
[2] – Cisco IOS Router Denial of Service Vulnerability
[3] – Cisco IOS HTTP Auth Vulnerability
[4] – Cisco IOS HTTP Configuration Arbitrary Administrative Access Vulnerability[5] – Cisco Catalyst SSH Protocol Mismatch Denial of Service Vulnerability
[6] – Cisco 675 Web Administration Denial of Service Vulnerability
[7] – Cisco Catalyst 3500 XL Remote Arbitrary Command Vulnerability
[8] – Cisco IOS Software HTTP Request Denial of Service Vulnerability
[9] – Cisco 514 UDP Flood Denial of Service Vulnerability
[10] – CiscoSecure ACS for Windows NT Server Denial of Service Vulnerability
[11] – Cisco Catalyst Memory Leak Vulnerability
[12] – Cisco CatOS CiscoView HTTP Server Buffer Overflow Vulnerability
[13] – 0 Encoding IDS Bypass Vulnerability (UTF)
[14] – Cisco IOS HTTP Denial of Service Vulnerabilit

Download and install the cisco-global-exploiter package from Github


To use this tool, type “ IPaddress number of vulnerability”

The following screenshot shows the result of the test performed on Cisco router for the vulnerability number 3 from the list above. The result shows the vulnerability was successfully exploited.

Cisco Auditing Tool

It is a PERL script, which scans Cisco routers for common vulnerabilities. To use it, again open the terminal on the left pane as shown in the previous section and type “CAT –h hostname or IP”.

Download  Cisco Auditing Tool Clone from GitHub
root@kali:~# CAT
Cisco Auditing Tool – g0ne [null0]
-h hostname (for scanning single hosts)
-f hostfile (for scanning multiple hosts)
-p port # (default port is 23)
-w wordlist (wordlist for community name guessing)
-a passlist (wordlist for password guessing)
-i [ioshist] (Check for IOS History bug)
-l logfile (file to log to, default screen)
-q quiet mode (no screen output)

You can add the port parameter “-p” as shown in the following screenshot, which in this case is 23 to brute-force it.

Scan the host (-h on port 23 (-p 23), using a password dictionary file (-a /usr/share/wordlists/nmap.lst):


Please only use this to exploit your own Cisco router and make sure you do not use it to exploit your local library’s Cisco router because We did use it against our local library’s Cisco router and it caused the library’s Internet to shutdown and remain disconnected for more than ten minutes!
